'l he inner end of boom is provided with foot castings l5 whereby lllfboom is pivotally attached through the medium of pins 16 to a turntablecenter 17 so as to be oscillatory about a horizontal axis, such centerbeing rotatable about a vertical aXis. Such turntable center l7, asshown in Fi 3, is tubular, being thus rotatably mounte on an innertubular post 18 that rests on a suitable deck in the superstructure 6that rises from base 1. lwo oppositely projecting lugs or ears 19 onsaid center provide means for attaching the foot castings of the boom tosuch center. Said center is also provided with a rearwardly projectingradial arm 20 which, as shown in Figs. 5 and 4, is of substantialconstructitm, preferably consisting of side plate 21. spaced apart whereattached to sa rl router and converging at their outer ends, said sideplates being connected together by means of top and bottom lates 22 and2;}. ()n the platform provided y the upp r plate romposing such arm 20is mounted a redu tion ear 25 adapted to be driven by an electric motor:26 supported on a Iatcralbv extending bracket 27, such reduction gearin luding a bevel driving pinion 28 that mr h with a bevel gear 29 fixedto the outer cntl of a \crticul shaft 30 journaled in the outer t-nd ofarm 20. i. e., at approximately th point wh re the side plate 21,forming part of such arm. come together. 'l'lai \\t'|' rn l ol saidshaft 30 is provided vv tb t spur pinion 31 that meshes with a'.it:oi.ar v internal annular gear 32 that is .rc-i y upported on thesame deck in supi i z-urturt- (3 that supports the boomturntabztt't'Illtl.

For the purpose of raising and lowering the outer end of boom 5 a lineor cable 35 iprovided, such cable passing from a suitable winding drum(not shown). that is. housed. alon; with the driving mechanism thcrcf'u. in the superstructure (l on base 1, around sheaves 36, 37 and 38,relatively stationarily mounted, as will be presently described, thencearound a sheave 39 attached to said boom near its outer end and aroundanother sheave 40 mounted like the firstnamed sheave, and so passingfinally to sheave 39 adjacent to which it i lixedl attached. Saidlast-named sheave is ecured to the boom through the medium of pivotalarms or links 41 capable of assuming various angular positions in avertical plane with respect to such boom. Sheaves 3(3 and 57. over whichthe line or cable 33 initially passes, are supported on fixed axes in aderrick-like tructure 42 that rises to a considerable height abovesuperstrtu-ture (5 so as to.

clear the hopper 9; while sheaves 38 and 40 are journalcd in a frame -13swiveled to the upper erd ol' said derrick about a vertical axis 44 thatis aligned with the axis of the boom turntable center. Sheaves 37,moreover, is so located that the cable as it passes on to sheave I38wili lie on the line of such axis. The boom, it will accordingly beseen, may be freely swung about the axis in question, irrespective ofits angular osition relatively to such axis, and conversely the outerend of the boom may be raised and lowered irrespective of the positionthe boom occupics in a horizontal plane.

For the purpose of conveying material delivered to hop er 9 from theinner to the outer end of the room, the latter is provided with anendless belt conveyor that passes around suitable sheaves or drums 51and 52 located adjacent its inner and outer ends, respectively. The rearend of the conveyor 50 will of course lie to the rear of the dischargeopening in hopper 9 so that the material delivered to the latter bye'levator 8 will be received onthe upper lap of such conveyor 50 and hecarried thereby along the boom until the outer end thereof is reached,whereupon the material will be discharged into a hopper-like receptacle53, from which depends a dischar 'e spout 54, the construction andmanner 0 mounting of which will require separate detail description.

The hopper 53 just referred to as constituting in effect the headsection of the discharge spout 54 is osci'llatorily supported in theouter end of boom 5 about the same axis 55 that constitutes the axis ofthe sheave or drum 52. In other words, irrespective of any swingingmovement imparted to such hopper or spout head. it will always remain inapproximately fixed relation to the discharge end of conveyor 50.Fixedly attached to such spouthead are two arms 56, one on each sidethereof. which arms project in .l general vertical direction toapproximately the same height above the boom 50, and two corresponding"arms 57 are fixedly mounted on the boom turntable center at the rear endof such boom. A light frame structure 58 is pivotal'ly attached at itsrespective ends to the uppcr ends of said two pairs of arms 56 and 57 soas to constitute Til in effect a link between the same, with the resultthat as the outer end of boom 5 is raised or lowered, said link 58 willcorrespondingly swing spout-head 53 so as to maintain the same at alltimes vertical; or what amounts to the same thing, the base of suchhead, from which the spout is directly supported, will be at all tunesmaintained horizontally.

The spout 5a is of telescopic construction, being composed of asufiicient number of sections to permit such spout to be extended orcontracted as may be found necessary in the particular field of usewherein the loading mechanism isemployed. For the. purpose of thuscontrolling the length of the spent, it is merely necessary to providemeans for raising or letting down, as the case may be, the outer section54 of said spout, the intermediate sections 54; belng arranged to bepicked up by each other, and finally by the outer section as the latteris raised. The inner telescoping section 54 of the spout is pivotallyhung about a transverse axis 60 from the underside of a platform (31that is rotatably secured about a vertical axis to the spout head 53 soas to constitute in effect a turntable support tor said spout. Fixedlyattached to said inner spout section 54 is an arm 62, that in the normalvertically depending position of the spout projects downwardly at anacute an le to the axis of the spout (see Fig. 2); ut by raising theouter end of arm '62 until it is brought approximately parallel withturntable platform til, the spout it will be seen, may be brought into aposition inclining at a corresponding acute angle from the horizontal.The actual angle between the spout and arm (32 will not be less thanthat at which the material being handled will flow l'rccly down thespout.

The manner in which the turntable platform (31. whereby the extensibledischarge spout .74 supported, is secured to the spout head, or in otherwords to the outer end of the boom, is best shown in Fig. 7. From thelatter it will be that spout head 53 is provided at its lower end with alateral flange (if) that forms a trackway for a series of rollers 66mounted about radially directed axes in a framework 07 thatrises fromsaid plat form. A complementary flange (38, likewise fixedly secured tothe spout head, hplds these rollers in place and thus ecuresthe platformagainst any tilting movement relatively to the spout head, while stillleaving it free to rotate about the axis of such spout head which, of'course, coincides w th the axis of thc spout when the latter depends innormal \ct'tlcal position.

For the purpose of controlling the length of the spout and for swingingarm 62 and thus the discharge spout about axis 60, as well as forrotating the platform 61 and thus Mm can the spout 54 the spout aboutthe vertical axis defined by the circular roller trackway which theflmges 65 and 68 constitute suitable cable connections are providedwhich will now be described in detail. It will be noted that t cables inquestion extend outwardly tl rough or above the boom 5 from drums (notshown) located at the inner end thereof and operated in any suitablemanner.

Since, due to its telescopic construction, normally tends under gravityto extend itself to its full length, it is merely necessary to provide acable for collapsing such spout, i. e. for raising the outermost sectionthereof. To this end, two sheaves 70 are attached to such outer section,one on each side thereof and so located transversely of the spout as toproject somewhat beyond the rear edge thereof, i. e. beyond the sidedirected towards arm 62. A second pair of sheaves 71 is hung in said armso as to be oscillatory about an axis 72 parallel with the common axisof said sheaves 70, while two other sheaves 73 are mounted on the shaftthat constitutes the axis 60, one on each side of the inner section 54of the spout. Mounted above and integral with roller flange 68 on thespout head is a periphorally grooved extension forming a fixed rin 74,while directl thereabove is a secon similarly groove floating ring 75that is held inv place by means of rollers 76 so as to be freelyrotatable about such spout head. Two sheaves 77 and 78, mounted on oneside of said spout head above ring 75, serve to guide a cable 79 ontothe latter. Said cable is carried one or more times around said ring andthence passes over relatively angularly disposed sheaves 80 and 81 inthe forward portion of turntable platform 61 onto one of the sheaves 73and so around one of the Sheaves 70, said sheaves 73 and 70 being theones on the n ar side, as shown in Fig. 7; then said cabl, passes overthe pair of sheaves 71 and sheaves 70 and 73 on the far side, as shownin said Fig. 7, back onto said fixed ring 74. a sheave 82 in theplatform on the spout head serving properly thus to guide the cableback. The end of the cable is carried around the ring a sufiicientdistance to insure against its ever being completely unwound, due lorotation oflhe platform, and is fixedly attached to such ring. It

As a result of the arrangement of sheaves and the manner in which thecable is passed around the same and around rings 74 and 75, as justdescribed, it will be seen that. as the platform is rotated in onedirection or the other, the cable on the near side will be unwound fromone of said rings and at the same time wound up on the far side on theother ring, or vice versa, so that the portion of said cable that liesbetween the two sheaves 70 and is loopel about the sheaves ill 71 willremain unchanged in length. However, the length of such loop may at anytime. i. e. iriespective ot' the angular position of the platform 61about its vertical axis of (l t'illtlti0ll. be increased by paving outsaid cable. or be decreased by drawing in on the same. The eliect oflengthening such looped portion of the (able T9 is, of course. to allowthe outer section 54 ot' the spout to drop and thus extend such spout,while conversely the etlect of shortening such cable will be to draw upsuch outer section of the spout and thus collapse the latter.

Substantially equivalent. means are proviihd t'or oscillating arm 62,and thus the spout ..l, and for retaining same in unchanged angularposition with respect to the platform. irrespective of any rotativemovement that may be imparted to the latter. Such means comprise asheave 90 secured to the outer end of said arm so as to be oscillatoryabout a transverse axis 91; two sheaves 92 and 93 adjacent the rear endof the platform, i. e. in that portion of the latter farthest removedfrom the spout head; a peripherally grooved ring 94 fixedly attached t0the framework wherein the spout head is supported; a similar ring 95rotatably mounted on such framework directly above ring 94; and sheaves96 and 97 lll0- wise mounted on said framework, one above the other but,with their axes at right angles to that of the rings just referred to.The lowermost sheave 96 of the two sheaves last referred to is mountedwith its lower edge aligned with the groove in the rotatable or floatingring 95, while the uppermost sheave 97 is 'referably mounted on the sameaxis as s eave 77 so as to receive a cable 98 that is carried out overthe boom substantially parallel with cable 79 that controls theextension and collapsing of the spout. From sheave 97 cable 98 passesover sheave 96 and one or more times around floating ring 95; thenceover sheave 93 down around sheave 90. back over sheave 92 and o to fixedring 94, around which it passes one or more times ant to which its endis fixedly attached. As in the case of the spout extending andcollapsing cable 79, so in the case of cable 98. gravity is relied uponto pay such cable out, i. e. to n rmally cause the spout to assume thevertically depending position shown in Figs. 1, 2 and T. liy drawing inon said cable, however. the portion thereof that lies between sheaves 9Land 93 and is looped about sheave will be out respoIuli:o :l hortened.with the result that the arm ti! 1. drawn up towards the tu n table til.i. e. into a more nearly horiz ntal position. aid the spout will beswung in a correspondin; direction from the vertical.

Furthermore. rotation of the turntable (it about its axis will have noetlect upon such angular position of the spout nor cau e the same to beswung from the vertic: l. that happens to be the position in which ithasv been left. inasmuch as the ca le will he wound up on the ti\ed rin;5H. and unwound ou the floating ring 95, or vice i'el'sa. an c.\' at-tlyequal amount, tints leai ing it all times the length of the loopedportion l Such cable that passes around fiiltiltti ill) unchanged. 4

For the purpose of rotating the turntable (it. there is fixedly attachedto the upper portion of the turntable frame (-7. so as to be in etiei-tintegral therewith. another peripherally grooved ring 100, surh ringbeing somewhat smaller in diameter than the rings 9t and 9:3 and beingconveniently located immediately above the latter of the rings justnamed. In order to properly guide onto such ring 100 the cable 101. thatserves thus to rotate said rin and through it. the turn table 61. twoguide :--heaves 192 are mounted on approximately the same axis butspaced from each other in the forward portion of the frame that supportsthe spout head 53, said sheaves being respectively disposed With theirlower edges on line with the lower and upper portion of the groove insaid ring 100. In addition to said sheaves 102, two other sheaves 103are mounted in said frame at a higher level, one on each side of thespout H head, (preferably on the same axis 55 as the sheaves 7 7 and97), over which the respec tive ends of the cable 101 are carried afterpasiiing around said sheaves 102 and 103, the intermediate portion ofthe cable being pas ed one or more times around the ring 100. In thecase of this cable 101 for rotatlng the platform (31, one end is, ofcourse, payed out as the other is drawn in. the ring 100 functioning asthe familiar bull-ring in the mounting of a. swinging boom or derriclc.
